A method for processing signals in a baseband processor of a handheld, wireless communication device, the baseband processor comprising an audio codec, a digital signal processor (DSP), a core processor and a memory, the memory being shared by the DSP and the core processor, the method comprising:

  • supporting multiple wireless communication protocols and multiple antennas;

    supporting separate processing paths for at least a general audio path, a voice path and a polyphonic ringer path before mixing the supported, separate processing paths;

    decimating a multi-level digital input signal by M, where M is an integer that is greater than or equal to 2; and

    generating an output digital signal having a number of signal levels greater than said multi-level digital input signal by processing said decimated multi-level digital input signal.
